Overview
- rPlus Energies announced on June 23, 2026, that the Green River Energy Center has begun commercial operations, supplying PacifiCorp with 400 MW of solar and a 400 MW/1,600 MWh battery.
- The project closed roughly $1.6 billion in financing, consisting of about $1.1 billion in construction debt and more than $500 million in tax‑equity commitments.
- Major suppliers and contractors include Tesla Megapacks for the battery system, Elite Solar for PV modules, Sundt Renewables as EPC, and Nextpower trackers with nearly one million solar panels installed.
- Project partners say Green River will produce over $55 million in property taxes over its life, funded hundreds of construction jobs, committed $375,000 in local scholarships, and donated $45,000 to the nearby Ferron Fire Department.
- As rPlus’s first utility‑scale asset, the center provides multi‑hour evening dispatch that can shift solar output into peak demand hours and could serve as a financing and supply‑chain model for more long‑duration storage projects in the U.S. West.
